Electronic Remote Controller with On/off control and 4 Spdt relay outputs
The T775 family of electronic remote temperature controllers provide on/off, modulating, or reset control in applications where electronic accuracy in addition to remote sensing is desired.
Available with one or two temperature inputs and up to four spdt relay output stages or modulating (electronic Series 90, 4-20 mA or 0-18 Vdc) outputs.
Typical applications include:-on/off control of fans, motors and heaters.-proportional and floating control of damper and valve actuators.-outdoor reset of heating and cooling systems.
Electronic control accuracy.
Linear platinum temperature sensor.
LCD display indicates mode and output status; jumper switch provides field selection of F or C display.
Keypad allows precise temperature selection; easy one-finger programming.
Remote sensing from up to 1000 ft. (304m).
Wide temperature setting range.
Adjustable differential and throttling range.
Heating and cooling stages independently programmable.
Available with NEMA 4X enclosure.
